United Utilities boss Steve Mogford said: "We are cutting bills such that they will be lower in real terms in 2025 than they were 15 years ago, whilst also delivering higher standards of service, increasing resilience, delivering innovation and investing for the long-term."

The utilities firm also said it will reduce capital expenditure by over £1 billion to £5.4 billion from 2020 to 2025.

The water regulator will assess the business plans and publish its findings in January.
